Vitor Belfort has lavished praise on Michael Bisping, labelling the British middleweight a "warrior" of the Octagon.

Belfort is in the veteran stage of his career, but still feels he is capable of fighting for UFC titles and will face Bisping at the UFC on FX event in Sao Paulo, Brazil on January 19.

The 35-year-old is back down to 185lbs, having tasted defeat to Jon Jones at light-heavtyweight in September. He feels sharp and ready for battle, but will not trash-talk Bisping.

"I think Michael is a great warrior," Belfort told ESPN. "He's one of the fighters who never picks his opponent. He'll fight anyone they put in front of him. He's very honourable to accept this challenge."

Bisping is in line for a crack at Anderson Silva if he beats Belfort, but the Phenom is not getting carried away by that prospect.

"I don't want to even talk about that," Belfort said. "It's none of my business. Pick fights, decide fights - the UFC has a puzzle. I'm part of that puzzle and I'm doing my part. I'm an employee.

"My job is to fight and be honourable to the organisation. I'm very honourable. I help the organisation when they need me. If I don't trust my promoter, why am I fighting for him? Dana knows what he's doing, so I'm happy."
